What the Bible says about Day of Lord as Unending Catastrophe
(From Forerunner Commentary)

Amos 5:19 One calamity occurs after another. It seems as if a person escapes one of them, only to become caught in a worse calamity. The Day of the Lord will be a time of unending catastrophe and trouble. John W.
